Abstract

a nickel-zinc ferrite material suitable for use in magnetic heads is disclosed. The material has a general empirical formula
(Ni.sub.1-y Zn.sub.y).sub.l-x Fe.sub.2+x O.sub.3.99
wherein x is less than 0 and greater than -0.040, y is from about 0.44 to about 0.58, and wherein the ratio of %NiO/%ZnO is from about 0.72 to about 1.27, and wherein the mole percent of NiO is from about 21.5 to about 28.5%, and the mole percent ZnO is from about 22.5 to about 29.5%, and the mole percent Fe2 O3 is from about 48 to about 50%. More specific composition ranges as well as a preferred composition are also disclosed.
